Second seed Federer improved to 8-0 lifetime against lucky loser Alejandro Falla with a 6-3, 6-3, 6-4 at the start of his 62nd straight Grand Slam championship.
Federer hit 42 winners, including eight aces, converting three of his 15 break point opportunities for victory in one hour and 49 minutes. He is now 62-15 at the clay-court major in Paris, where he lifted the trophy in 2009 (d. Soderling), and he will next challenge Marcel Granollers in the second round. Granoller beat Matthias Bachinger 6-4, 6-3, 7-6.
Roberto Bautista Agut, the No. 19 seed, hit 35 winners in a 6-3, 6-1, 6-3 victory over Florian Mayer and is now one victory away from equalling his best performance. Last year, he lost in the third round to Tomas Berdych. The Spaniard goes on to face Lukas Rosol, who was a 6-2, 7-6(7), 6-3 winner over Elias Ymer.
Philipp Kohlschreiber, the No. 22 seed, cruised past Go Soeda 6-1, 6-0, 6-2.
Swiss man, Stan Wawrinka also began his bid to win the French Open title with a win over Marsel Ilhan on Sunday at Roland Garros.
The eighth seed hit 42 winners and saved all six break points he faced to win 6-3, 6-2, 6-3 in one hour and 36 minutes.
Last year, Wawrinka fell to Guillermo Garcia-Lopez in his opener to become the first reigning Australian Open champion to lose in the first round at the subsequent Roland Garros since Petr Korda in 1998.
Wawrinka awaits the winner of Dusan Lajovic and Maximo Gonzalez.
Marcos Baghdatis, whose best showing in Paris was a fourth-round berth in 2007, beat No. 25 seed, power-serving Ivo Karlovic 7-6(5), 6-4, 6-4. He will next face Damir Dzumhur.
